The adhesive wheel 1710 is used for bonding the corner of the top layer of the single sticker product to the corner of the adhesive paper, so that the bottom layer of the single sticker product is exposed at the corner. Under the driving action of the first translation driving mechanism 1600, the adhesive wheel 1710 reciprocatingly moves along the diagonal line of the top plate 1500 and bonds and tears the corner of the single sticker product.

[0039] The tear corner gap is provided at the corner of the top plate 1500 to provide space for the adhesive wheel 1710, and under the driving of the lifting driving mechanism 1300 and the first translation driving mechanism 1600, the adhesive wheel 1710 can lift the corner of the adhesive paper on the top layer of the single sheet sticker product, thereby exposing the corner of the release film on the bottom layer. The rotation driving mechanism 1400 can drive the corner of the release film to reach the clamping area of the clamping mechanism 2200, the clamping mechanism 2200 can clamp the corner of the release film, and the second translation driving mechanism 2100 can drive the clamping mechanism 2200 to translate to tear the release film from the adhesive paper below. The vacuum adsorption hole 1510 ensures that the adhesive paper is fixed on the bottom surface of the top plate 1500, which can effectively improve the stability of the film tearing action, and can effectively reduce the probability of misalignment, wrinkles and other problems caused by movement, vibration and other actions. The release film is torn from the corner position, which can further improve the stability of the film tearing action, and only the adhesive wheel 1710 with adhesion is needed to roll and adhere to the corner position to provide a tear hand part for the clamping mechanism 2200, which can effectively reduce the difficulty of film tearing, and the film tearing action is stable and reliable, the film tearing efficiency is high, the film tearing effect is good, the automation degree is high, and the labor cost is low. It can effectively reduce the adverse effects caused by manual operation;

[0040] In addition, the charged particle airflow is delivered to the bottom surface of the adhesive paper after film tearing through the ion wind hole 1210, which can effectively neutralize the static electricity formed on the surface of the adhesive paper after film tearing. It not only can effectively reduce the adverse effects on FPC circuit during pasting, but also can effectively improve the flatness and reliability during pasting, can effectively reduce the probability of generating bubbles and other defects, can form a good film pasting basis, and the ion wind hole 1210 is integrated in the bottom plate 1200, which can effectively improve the space utilization of the whole device, and the structure is compact and reliable.

[0041] Specifically, the lifting driving mechanism 1300 can be set as a lifting cylinder, the rotating driving mechanism 1400 can be set as a rotating motor, the first translation driving mechanism 1600 can be set as a translation cylinder, and the second translation driving mechanism 2100 can be set as a screw rod mechanism or a linear driving platform.

[0042] It can be understood that the clamping mechanism 2200 comprises a translation plate 2210, a rotating motor 2220, and a pneumatic finger 2230, the pneumatic finger 2230 is also known as a pneumatic clamping jaw or a pneumatic clamping finger, is an execution device for clamping or grabbing workpieces by using compressed air as power, the translation plate 2210 is connected to a translation driving end of the second translation driving mechanism 2100, the rotating motor 2220 is connected to the translation plate 2210, a shell of the pneumatic finger 2230 is fixedly connected to a rotating driving end of the rotating motor 2220, preferably, the shell of the pneumatic finger 2230 is further connected to the translation plate 2210 through a rotating bearing, the rotating motor 2220 is used to drive the pneumatic finger 2230 to rotate in a direction parallel to the horizontal plane, a rotating shaft of the pneumatic finger 2230 is parallel to the horizontal plane, and the rotating shaft of the pneumatic finger 2230 is perpendicular to a driving direction of the second translation driving mechanism 2100, a clamping part of the pneumatic finger 2230 faces the upward of the bottom plate 1200, and the pneumatic finger 2230 is used to clamp a corner of a release film at a bottom layer of a single sticker product.

[0043] In work, the pneumatic finger 2230 clamps the corner of the release film; the rotating motor 2220 drives the pneumatic finger 2230 to rotate, which can effectively improve the stability of the pneumatic finger 2230 in clamping the corner position of the release film, and can effectively avoid the release film from being separated from the clamping of the pneumatic finger 2230 in the film tearing process; the second translation driving mechanism 2100 drives the translation plate 2210, the rotating motor 2220, and the pneumatic finger 2230 to synchronously translate from one side of the top plate 1500 to the other side, which, in cooperation with the vacuum adsorption holes 1510 at the bottom of the top plate 1500, can tear the release film from the bottom surface of the sticker, and the film tearing action is stable and reliable.

[0044] It can be understood that the clamping mechanism 2200 further comprises two clamping plates 2340, each clamping plate 2340 is connected to two clamping parts of the pneumatic finger 2230, the translation plate 2210, the rotating motor 2220, and the pneumatic finger 2230 are all located outside one side of the bottom plate 1200, and the horizontal projection of the translation track of the two clamping plates 2340 all intersects with the horizontal projection of the adhesive, so as to ensure that the film tearing action can be smoothly performed, the overall structure is compact and reliable, and the clamping plates 2340 replace the pneumatic finger 2230 to contact the release film, which can effectively and conveniently design the overall structure layout.

After clamping is completed, the turnover motor 2220 drives the pneumatic finger 2230 to rotate, so that the two clamps 2340 reach below the top plate 1500, ensuring that the two clamps 2340 can be translated between the top plate 1500 and the bottom plate 1200 under the drive of the second translation drive mechanism 2100, and the overall film tearing processing action is coherent and reliable.

[0047] It can be understood that the bottom plate 1200 also has an ion chamber 1220 and a positive pressure channel 1230, and the pre-tearing assembly 1000 further includes a plurality of ion generators 1240. The ion generator 1240 generates negative ions by using a high-voltage transformer to step up the power frequency voltage to the required voltage, thereby releasing charged particles into the surrounding air. The output end, i.e., the ionization end, of each ion generator 1240 is arranged in the ion chamber 1220. The bottom end of each ion air hole 1210 communicates with the ion chamber 1220, and the top end of each ion air hole 1210 penetrates the top surface of the bottom plate 1200. One end of the positive pressure channel 1230 communicates with the ion chamber 1220, and the other end of the positive pressure channel 1230 is used to connect an external positive pressure fan or ion fan 1210, which can effectively improve the effect of the ion air hole 1210 outputting charged particle airflow and effectively improve the neutralization effect on the surface charge of the adhesive paper.

[0048] It can be understood that the top plate 1500 also has a vacuum chamber 1520 and a negative pressure channel 1530. The bottom end of each vacuum suction hole 1510 communicates with the vacuum chamber 1520, and the top end of each vacuum suction hole 1510 penetrates the bottom surface of the top plate 1500. One end of the negative pressure channel 1530 communicates with the vacuum chamber 1520, and the other end of the negative pressure channel 1530 is used to connect an external vacuum generator or negative pressure fan, which can form a negative pressure environment in the vacuum chamber 1520 and the vacuum suction hole 1510, thereby adsorbing the top layer of the single sheet of adhesive paper product to the bottom surface of the top plate 1500.
